While OMAP's iovmm (virtual memory manager) driver does not strictly belong to the iommu drivers folder, move it there as well, because it's by no means OMAP-specific (in concept. technically it is still coupled with the omap iommu), and exposing it will ease its generalization, consolidation, or removal (once a generic virtual memory manager and allocator would materialize). Move omap's iommu debug driver to the generic folder as well, for the same reasons.
